"There is a limit to killing people, and all ethnic groups have their own borders. If we can control the invasion of the mausoleum, how many people will be killed? " Poet's speech is generous, and he speaks his mind directly, hit the floor. In his view, keeping Qiang Bing is only for guarding the border, not for fighting. Whether "shooting horses" for the enemy, "killing people" for necessity, or "capturing the king" for Qiang Bing, it should be limited to "controlling the invasion of the mausoleum", not to mention arrogantly invading foreign countries. This idea of fighting with war and stopping aggression with Qiang Bing is a grand theory and a good strategy to ensure border security; It reflects the interests of the country and the wishes of the people. Therefore, Zhang Hui said in "Du Fu Yao" that these words are "big classics, spoken by guards".
From the perspective of artistic conception, the author adopts the method of promoting first and then restraining: the first four sentences are based on popular and philosophical proverbs, telling how to train and use soldiers and how to defeat the enemy; The last four sentences are about how to control martial arts, try to avoid a war and force out the original intention of "stopping fighting for martial arts" Auxiliary pen first, then main pen; Between the auxiliary pen and the main pen, it seems to be sweeping, but in fact it is connected, seemingly contradictory, but actually dialectical. Because there is no reliable armament, it is impossible to stop foreign aggression; However, it is not advisable to rely on strong armed forces and resort to belligerence. Therefore, the poet advocates both supporting Qiang Bing and "controlling the invasion of the mausoleum", which is in line with the interests of the vast majority of people. Pu Yin Long read Du Xin Jie and said with great insight: "The above four sentences were so soaring, and the following four sentences were suddenly swept away, and the rabbits fell down. It really happened! If so! " The "soaring" and "sweeping" mentioned here refer to the surging momentum and waves in the works; The "rabbit rises and falls" mentioned here refers to the profound theme of "supporting and opposing weapons" naturally revealed in the momentum of Pentium. In the Tang dynasty, there were few works that won by argument, but this poem was famous for its argument; It has won high praise for its lofty ideas, honest and frank attitude, philosophy and grandeur.
Han Yuefu has songs "Out of the Frontier" and "Into the Frontier", which are about the fighting life in the frontier. Tang people often write frontier poems with fortresses as the theme. Du Fu wrote many songs, the first nine of which were called "Before the Dyke" and the last five were called "After the Dyke". In the last years of Tianbao, Geshuhan was blamed for being greedy for Tubo, while An Lushan blamed the Khitan, so he clamored for a long time. Great war disasters and burdens fell on the people. By focusing on the process of a soldier guarding the border for ten years, it reflects the deep suffering brought to the people by the border war launched by the Tang Dynasty and satirizes Xuanzong's belligerent policy. This group of poems is written in the first person, grasping the personality characteristics of the characters, paying attention to psychological depiction, with a compact structure and orderly levels, and nine poems are integrated. Here is the sixth song. The poem not only expresses the intention of opposing militancy, but also expresses the idea of solving frontier problems through political means. "A Detailed Interpretation of Du Fu's Poems" says: Sigh for the militaristic behavior at that time. Zhang Wan's Note: The meaning of the chapter is only in the sentence "capture the king". The first three sentences are suggestive, and the last four sentences state that there is no need to kill indiscriminately.
The style of this poem is like ballads and proverbs, and it is the most beautiful scenery in Yuefu (Du Shi said).
